Naturally many of the users of this stackexchange site are going to be observant Jews who keep the laws of Shabbat. This means that many users will not be using the site at all for one day a week. Does this put us at a disadvantage in general and is there any way to make sure that this fact is noted when being evaluated as a beta site? I would be interested in knowing if there was any reflection of this type of drop in traffic during the mi.yodeya days.
On the other hand, the "professional" Stacks also have substantial dip over the weekends.
"Professional" i.e. not the hobbyist sites such as RPG, Boardgames, etc. Rather the programming sites, DBA, PM, Security, etc...
I can speak for ITSecurity.SE, weekends (Sat. and Sundays) drop down to near ghosttown levels, then bounce back up.
Overall, the SEI folk seem to look more at the trending, and not specifics of a given day(s).
So, I wouldnt worry about it.
To your last point, here's a graph from mi.yodeya's hit counter for April 2011.
You can see significant dips on:
- Sabbaths: April 2, 9, 16, 23, and 30
- Passover first days: April 19 and 20 (latter less so because only observed outside of Israel)
- Passover last days: April 25 and 26 (latter less so because only observed outside of Israel)
It will definitely make it hard (but not impossible) to get the Enthusiast badge
